Not quite another 9 years, but more like 2 -1/2 years later I was perusing the site and can report that the seal is still holding up well. That's more than 25 years since I replaced it, longer than the original seal lasted. If anybody develops a countershaft oil seal leak and needs anything clarified about my shade tree time and aggravation saving seal replacement, feel free to contact me anytime. Cheers and Happy New Year to all.

Well, here's the first installment on the next 9 year report. It's only about 2 years later, but no surprise - the countershaft seal is still good, far outlasting the original one. Did a 220 mile ride today with a local riding club. After some work last week I got rid of the last oil leak and can report there are no new ones. Over the decades I have had leaks from the oil filter housing, cam end covers and an initially puzzling one caused by a pulled case stud (TimeSerting the case resolved that many years ago), as well as the countershaft seal leak. Finally NO spots on the garage floor.
